How Is Tungsten Mined?

Tungsten is primarily mined from two types of ore deposits: scheelite and wolframite. These deposits are found all over the world, with the largest producers being China, Russia, Canada, and Bolivia.

Scheelite is a calcium tungstate mineral with the chemical formula CaWO4. It typically occurs in various colors, including white, yellow, brown, and shades of green. Scheelite is an important ore mineral of tungsten and is primarily found in hydrothermal veins and greisen deposits. It often forms as tabular or prismatic crystals and has a high specific gravity. Scheelite is valued for its relatively high tungsten content and is a major source of tungsten used in various industrial applications.

Wolframite, on the other hand, is an iron-manganese tungstate mineral with the chemical formula (Fe,Mn)WO4. It is a solid solution series between the end members ferberite (FeWO4) and hübnerite (MnWO4). Wolframite is typically black or brown in color and is commonly found in quartz veins and pegmatites. It often occurs as elongated prismatic crystals or in dense aggregates. Wolframite is a significant source of tungsten and is commonly mined alongside other minerals, including cassiterite (tin ore). Its tungsten content makes it an important ore for the production of tungsten metal and tungsten alloys.

Both scheelite and wolframite are crucial sources of tungsten and are mined for their tungsten content. The extraction and processing of these minerals play a vital role in meeting the global demand for tungsten in various industries.

Tungsten mining involves several stages, beginning with prospecting and exploration to identify potential tungsten deposits. Once a suitable site is found, the mining process begins. The most common method of tungsten extraction is open-pit mining, particularly for large-scale operations. This process involves the use of heavy machinery, such as excavators and bulldozers, to remove the overlying soil and rock, exposing the tungsten-bearing ore. In some cases, underground mining may be employed, especially if the deposit is deeper or the ore quality justifies the additional cost. Underground mining utilizes tunnels and shafts to access the ore bodies.

Once the ore is extracted, it is then crushed into smaller pieces to facilitate further processing. The next step typically involves the beneficiation process, where the crushed ore undergoes physical or chemical treatments to separate the tungsten minerals from the waste materials. This can involve methods such as gravity separation, flotation, magnetic separation, or a combination of these techniques, depending on the specific ore characteristics.

After beneficiation, the resulting concentrate is further processed through various refining techniques. The most common refining method is roasting, where the concentrate is heated in the presence of air to remove impurities and convert the tungsten minerals into tungsten oxide (WO3). This oxide can then be chemically processed to obtain pure tungsten metal through a reduction process using hydrogen or carbon.

Overall, tungsten mining involves a series of steps, including prospecting, extraction, crushing, beneficiation, and refining, to transform the raw tungsten ore into a usable form for various applications.

Common Tungsten Forms

Tungsten is found in various forms depending on its application and processing. One of the most common forms is tungsten oxide (WO3), which is produced during the refining process of tungsten ore. Tungsten oxide is a yellowish or bluish powder that serves as a precursor for the production of tungsten metal. It is also used in the production of tungsten alloys and as a catalyst in certain chemical reactions. Another common form is tungsten carbide (WC), a compound composed of tungsten and carbon. Tungsten carbide is extremely hard and is often used in the manufacturing of cutting tools, drill bits, and abrasives. It is known for its exceptional wear resistance and is highly valued in industries such as mining, construction, and machining. Additionally, tungsten alloys are widely utilized in various applications. These alloys typically contain tungsten along with other elements such as nickel, copper, iron, or cobalt. Tungsten alloys are sought after due to their high density, excellent strength, and good thermal and electrical conductivity, making them suitable for applications in aerospace, defense, electrical contacts, and radiation shielding.
